Let’s be clear from the start: Sony sold its VAIO division in 2014. The official driver pages are gone. You are now in the "digital archaeology" phase of PC ownership.
This laptop uses NVIDIA Optimus (switching between Intel and NVIDIA). Windows 7 natively supports this well, but you must install the Intel HD Graphics driver before the NVIDIA driver, or use the NVIDIA package which handles both automatically.
Disclaimer: Always ensure you download drivers from the official Sony website or trusted sources. While Windows 7 is a legacy OS, keeping drivers updated ensures your hardware remains secure and functional.
